To display digital channels as a bus
Digital channels may be grouped and displayed as a bus, with each bus value displayed at
the bottom of the display in hex or binary. You can create up to two buses. To configure
and display each bus, press the [D15-D0] key on the front panel. Then press the Bus
softkey.
Next, select a bus. Rotate the Entry knob, then press the Entry knob or the Bus1/Bus2
softkey to switch it on.
Use the second softkey from the left and the Entry knob to select individual channels to
be included in the bus. You can rotate the Entry knob and push the softkey to select
channels. You can also press the Select/Deselect D15-D8 and Select/Deselect D7-D0
softkeys to include or exclude groups of eight channels in each bus.
If the bus display is blank, completely white, or if the display includes “...”, you need to
expand the horizontal scale to allow space for the data to be shown, or use the cursors to
display the values (see page 382).
The Base softkey lets you choose to display the bus values in hex or binary.
